It's late evening. Sun Tian is using her smartphone do her homework. The 15﹣year﹣old girl from Zhejiang uses an app to read English articles according to her teachers instructions.
These days, it's normal for teachers to give homework on apps. For example, students are asked to practice English or do math exercises. Some teachers also use Wechat chat groups to give homework. Bu now, Zhejiang province is moving to ban(禁止)teachers from giving homework on mobile apps because they worry about students' eyesight. More than 70 percent of middle school students in China are found to be nearsighted, according to the World Health Organization. Using mobile phones for long periods of time is bad for our eyes.
Do students like to do their homework on their phones？Zhang Hua, a 13﹣year﹣old boy from Fujian, said he doesn't. "Sometimes the apps can't recognize what I'm reading in English. I have to work on them for a long time to get a high score, "he said. He said his eyesight has gotten worse since he started using apps to do his homework.
However, Wang Xidi, from Anhui, 15, enjoys doing homework on apps. "The apps have big databases(数据库)of math exercises！And I can revise(修改)my answers easily, "She said. "But the bad part is that I can't help playing with other apps while doing my homework."
Zhou Tianyi, 12, from Sichuan, also thinks it's fun to do homework with apps. Her teachers ask their students to dub(配音)English videos and make their own short videos. "But if I have too much other homework to do, I feel like it's too much for me to finish, "she said.
